Background: Data on stroke epidemiology and availability of hospital-based stroke services around the world are important for guiding policy decisions and healthcare planning. Aims: To provide the most current incidence, mortality and case–fatality data on stroke and describe current availability of stroke units around the world by country. Methods: We searched multiple databases (based on our exi
During recent years, many sites with sediments pre-dating the Last Glacial Maximum have been identified in formerly glaciated areas. As more and better dates are presented from these sites, the dynamic behaviour of the Scandinavian Ice Sheet is becoming increasingly clear. In this study, we revisited the site Skorgenes in western Norway. Here, sediments from two ice-free periods are found below an
This paper presents a wideband quadrature radio receiver employing ΔΣ-based A/D-converting channel-select filters (ADCSFs). The output of the quadrature passive mixer is directly connected to the input of the ADCSFs, where a first-order ΔΣ modulator is incorporated into a fourth-order Butterworth channel-select filter (CSF) to provide sufficient dynamic range for a cellular system. A design method
Pile heat exchangers are fast emerging as a potentially viable alternative to the more prevalent borehole heat exchangers for the provision of space heating and cooling. In the last decade or so, the use of geothermal piles has increased sharply in many countries including Belgium, China, Japan, Switzerland, the Netherlands, United Kingdom, and United States, among others. In Sweden, however, inte
Levulinic acid (LA) is considered to be one of the promising organic bio-platform chemicals and intermediates for the synthesis of fuels, chemicals, and polymers. In the present study, heterogeneous catalytic dehydration of hexose sugars, fructose and glucose, using a strong cation exchange resin (hydrogen form) as an acid catalyst, was performed to produce LA in an aqueous medium. The effect of s
Most previous studies about fertility knowledge and attitudes among men have been based on quantitative methods using questionnaires with fixed-choice response options. The aims of this qualitative study were to explore childless young men’s reflections on fertility and infertility through semi-structured interviews. Danish (n = 17) and Swedish (n = 12) young childless men aged between 20 and 30 y
Gene therapy approaches using viral vectors for the overexpression of target genes have been for several years the focus of gene therapy research against neurological disorders. These approaches deliver robust expression of therapeutic genes, but are typically limited to the delivery of single genes and often do not manipulate the expression of the endogenous locus. In the last years, the advent o
Purpose: For exercise testing of COPD patients, a standard endurance test (ET) with constant workload is recommended. The test suffers from large inter-individual variability and need for large sample sizes in order to evaluate treatment effects. Methods: A new protocol for ET in COPD was designed. In contrast to the standard ET, the new ET involved an increasing workload in order to reduce the st
Zone plates are diffractive optics commonly used in X-ray microscopes. Here, we present a wet-chemical approach for fabricating high aspect ratio Pd/Si zone plate optics aimed at the hard X-ray regime. A Si zone plate mold is fabricated via metal-assisted chemical etching (MACE) and further metalized with Pd via electroless deposition (ELD). MACE results in vertical Si zones with high aspect ratio
Four in-line tube bundles with different geometry were investigated for establishing their performance in terms of heat transfer enhancement. Two-phase aqueous foam was used as a coolant. Such coolant was considered, because our previous research showed that large heat transfer intensity may be reached even at small mass flow rate of the foam. Spacing among the centres of the tubes across the firs
The problem of empty names derives from the fact that empty names fail to refer. The reference failure of empty names implies that sentences containing empty names lack truth-conditions. As a consequence those sentences are meaningless, according to many theories of meaning. The present dissertation addresses the problem of empty names and proposes a solution to the problem at hand. In brief, the
Part I of the dissertation examines the cognitive aspects of autonomy. The central question concerns what kind of cognitive capacity autonomy is. It will be argued that the concept of autonomy is best understood in terms of a metacognitive capacity of the individual. It is argued that metacognition has two components: procedural reflexivity and metarepresentation. Metarepresentation in turn can be
In concrete most cracks start from an uncracked surface and grow through a large portion of the depth of the specimen. Both formation and growth are influenced by stresses from imposed deformations, shrinkage, temperature etc. Thus fracture mechanics, when applied to concrete, should be able to analyse the following: 1. The formation of a crack in a specimen which is not notched or precracked. 2.
Many problems concerning resource management in modern communication systems can be simplified to queueing models under Markovian assumptions. The computation of the optimal policy is however often hindered by the curse of dimensionality especially for models that support multiple traffic or job classes. The research focus naturally turns to computationally efficient bounds and high performance he

Denna uppsats utreder vad samhällskontraktet är enligt Thomas Hobbes och John Lockes olika teorier. Den undersöker också möjligheten att lämna samhällskontraktet och om det idag finns exempel på grupper som försöker lämna det. Samhällskontraktsteorin är en rättsfilosofisk teori som försöker besvara frågan varför människor underkastar sig någon annan när de från början är fria människor. Hobbes ochThis essay examines what the social contract is according to Thomas Hobbes and John Locke’s different theories. It also examines the possibility of leaving the social contract and if there groups that are trying to leave the contract currently exist. The social contract theory is a legal philosophical theory that tries to answer the question of why humans submit to another when they originally are
Artificiell intelligens (AI) är inget nytt fenomen, men förkom redan på 1950 talet. Mer nyligen under 2014 redovisades ett nytt ramverk för generativ AI. Systemet kan generera realistiska bilder som simulerar både konstverk och människor. Fördelarna med AI går inte att förneka, såsom att förbättra våra liv. AI kan däremot leda till oönskade utvecklingar. Under 2023 upptäckte organisationer som arbArtificial intelligence (AI) is not a new phenomenon but has been in existence since the 1950s. More recently in 2014 a new framework for generative AI was developed. The system can generate realistic images that imitate both works of art and people. The benefits of AI are undeniable, and that AI has the capacity to greatly improve our lives. However, AI may also result in unwelcome developments.
This thesis will explore Roman religion of the imperial time from 29 BCE until the 370’s CE as an alternative lens to enhance the academic discourse on political religion. As a case study, Marxism-Leninism which was the guiding ideology of the former German Democratic Republic (GDR) will be analysed. According to Emilio Gentile, a political religion is characterised by six criteria. It shall be (1
